I tired to rotate the picture but it didn\'t work for some unknown reasons!

Shown to the right is a scatter plot that indicates a relationship between the percentage of adult females in a country who are literate and the mortality of children under five (per thousand). Also shown is a line that passes through or near the points. Find a linear function that models the data by finding the slope-intercept form of the line\'s equation. Use the function to make a prediction about child mortality based on the percentage of adult females in a country who are literate. Using the indicated points on the graph of the line, find the slope-intercept form of the lines equation. Use the percentage of adult females who are literate as the x - value f(x) = (Use integers or decimals for any numbers in the equation.)

Solution

To find slope intercept form of equation we need to points

we have (0, 260) and (60, 176)

slope = (176 -260)/(60 -0)

= -84/60 = -21/15 = -7/5

y = -7x/5 +c .Find c using any 1 point ( 0, 260)

c = 260

So, Slope intercept equation of line : y = -7x/5 +260

It can be inffered from the equation that as the female literacy increases , infant

mortality decreases
